Answer 1

I guess you are trying to create empty int array and then asking user to enter value in array.

{
Scanner sc = new Scanner (System.in);
int [] name = new int [6];
for(int x: name){
name[x] = sc.nextInt();
} }

Answer 2

Can't assign array elements' values by using enhanced for...loop. You'd probably have to use regular for...loop and index to assign array elements' values.

Answer 3

Try something like this:

import java.util.Scanner ;
public class Program
{
public static void main(String[] args) {
int n;
Scanner sc=new Scanner(System.in);
System.out.print("Enter the number of elements you want to store: ");
//reading the number of elements from the that we want to enter
n=sc.nextInt();

//creates an array in the memory of length 10
int[] array = new int[10];
System.out.println("Enter the elements of the array: ");
for(int i=0; i<n; i++)
{
//reading array elements from the user
array[i]=sc.nextInt();
}

System.out.println("Array elements are: ");
// accessing array elements using the for loop
for (int i=0; i<n; i++)
{
System.out.println(array[i]);
}
}
}
